摘要： A thermal flow meter corrects flow rate detection errors produced by vaporization of liquid phase components included in a gas to be measured. The thermal flow meter includes a correction circuit 500 that applies respectively different predetermined voltages to heating resistors consisting of first heating resistor Rh1 and second heating resistor Rh2 of a sensor element disposed in the gas to be measured to set a first temperature state and a second temperature state, calculates a first flow rate value Q1 of the gas to be measured in the first temperature state and a second flow rate value Q2 of the gas to be measured in the second temperature state, and calculates a flow rate correction value ΔQ based on a ratio (Q1/Q2) between the first flow rate value and second flow rate value or a fourth-power value (Q1/Q2)4 of the ratio to correct a flow rate of the gas to be measured.

摘要： There is provided a thermal type flow meter capable of accurately detecting a flow rate even when a fluid temperature varies rapidly or when the fluid temperature is high. A probe includes: a first main heating resistor; a second main heating resistor set at a temperature different from that of the first main heating resistor; and a sub-heating resistor for heating lead wires of the two main heating resistors. A CPU of a sensor control circuit finds a fluid temperature by using the two main heating resistors, and finds a fluid flow rate by using at least one of the two main heating resistors.

摘要： An injection control unit of a fuel is provided, which prevents generation of a nozzle deposit of a fuel injector. In a control unit of a fuel injector capable of controlling a lift height that is a distance between a valve body and a valve seat, after start of fuel injection and before end of the fuel injection, after the lift height is controlled to a first height, a period in which the lift height is controlled to a second height which is lower than the first height is provided for a predetermined period. According to such a configuration, when the lift height of the valve body is lowered to the second height after the fuel is injected at the first height, a fuel velocity in the vicinity of an inner wall of an injection port is increased due to an inertial force of the fuel and reduction in an opening area. By a fuel flow at a high velocity, a contamination substance adhering to a wall surface is washed away.

摘要： A control device for an internal combustion engine that is capable of easily switching between a stratified operation mode and a non-stratified operation mode is provided for a port injection spark ignition internal combustion engine. Injection directions in which sprayed fuel is injected from a fuel injection valve are defined nearer the center of a cylinder than the centers of two intake valves. Injection timing of the fuel injection valve is controlled by the stratified operation mode completing the fuel injection in the exhaust stroke, and the non-stratified operation mode completing the fuel injection in a range from a compression stroke to the exhaust stroke. The injection end timing of the fuel injection valve in the stratified operation mode is retarded from the injection end timing in the non-stratified operation mode, in which the fuel injection time is equal to or shorter than that in the stratified operation mode.
